IMPROVED SPRING-BED BOTTOM The Schedule referred to in these LettersPatent and making part of the same.

To all whom it may conce/m v Be it known that I, WILLIAM HAWORTH, ofCanton, inthe county of Stark, and State of Ohio, have invented new anduseful Improvements in Spring- Beds; and I do hereby declare that thefollowing is a full, clear, and exact description of my invention,reference being had tothe accompanying drawings, forming a part of thisspecification, and to the letters of reference marked thereon, of whichdrawings- V Figure 1 is a sectional elevation of my improved spring-bed.

Figure 2 is a half plan of the same.

Figure 3 is a cross-section of the same.

n Figure 4 is an elevation of the frame-pawl.

My invention relates to certa-in improvements in the construction ofspring-beds.

The nature of my invention consists in the combination of anelastic-wire rim with a set of'conioal spiral springs, arranged withtheir smallei ends downwards, and resting upon a set of elastic slats,said spiral springs and elastic slats being so constructed as to unitetheir elastic movements in allowing a movement of the bedsurface, andsaid elastic rim forming aline of elastic resistance to the tension ofthe cords, uniting the tops of the spiralsprings, whereby I obtain avery light, elastic, and cheap spring-bed.

To enable others skilled in the art to make and use my invention, I willproceed to describe'its constructien and operation.

ihe main frame of my'bedlis composed of the sideiief-.es G G andcross-pieces H N, which form aframe oi' a size a little less than thatof the interior of the hedstead for which the bed is designed, and whichrest on blocks, or cross-slats arranged in said bedstead in an ordinarymanner.

The cross-bar I is secured to the side-pieces G G, as shown, and theelastic slats J J are laid over this cross-bar I, their upper ends beingsecured by nailsor screws to the upper frame-piece N, while their lowerends rest on the lower frame-piece H, where they are prevented frommoving sideways, and, at the same time, are allowed an end motion toadmit of their bend' ing, by means of the pin k in frame-piece H, andslot l in the slats J, as shown in ligs. l and 2.

On the frame-pieces G H G, are arranged, on the edge, springs B B, asshown, while the centre springs A A are secured to the elastic slats JJ, as shown in figs. 1, 2, and 3.

These springs A B are of the conical formshown, instead of having thedouble conical form common to most spring-beds, and are placed withtheir small ends downward, thus bringing the weight ofthe person on tothe large and most elastic part of the spring iirst, and insuring theeasy action of the spring, without that noise caused by the coils of thespring coming down on the slats, which would occur in using a halfspring with the small end upward in this class of beds.

The elastic slats J J are so constructed Awith reference to the springsA A, as that they shall be of such cross-section as will allow ofY theirspringing -freely whenever the weight of an ordinary person is broughtto bear on the springs A A, from which it is readily seen that theelasticity of the bed is due,'first, to the elasticity ofthe springs A,and second, :to that of the slats J, and that, by this means, the samesurfaceelasticity for the bed can be had much cheaper than where thedouble conical-formed bed-springs are used, as the spring-Slat J answersboth as the equivalent of the lower half of the double conical spring,and also as the slat, or its equivalent, 'for support of spring, whichwas necessary in the old mode of constructing beds with double conicalsprings.

The elastic wire rim E extends around the top of the outside springs BB, and has its ends e secured to the blocks b on the frame-pieces G, asshown.

'Ihe cordingp lr s, which unites the several springs,

is represented by red lines in figs. 1, 2, and 3, from rim E, andframe-piece H, and the cords p serve as braces to aid in keeping thesprings in-their correct position.

The transverse cords r run from the frame-piece G- to the top of sidespring B, where they are knotted to hold the spring B and rim Etogether, and from there they are knotted into the springs A A acrossthe bed, to the opposite spring B, where they unite said spring and rimB, and are then secured to frame-piece G, as seen in tig.A 3. f Thecords t t serve as braces to check the side movement of thesprings B A AB. l

It is readily seen that as the rim E is made of elastic wire, it willgive easily, and allow the springs A A to play freely in any position,which would not be the case were the cords ofr attached to a rigid rim,and that it allows a free motion t0 the side springs B, which makes theedge of the bed very elastic, and that the use of this rim 11), of lightwire, renders the whole bed much cheaper and'lighter, as it dispenseswith the necessity of any side upright box-pieces to the bed, and thatthis dispensing with the side box-pieces allows the springs A B to closenp their whole length, if need be, thus obtaining thewhole elasticheight of the springs, and avoiding the length of spring necessary in'the old forms ofspring-beds.

The head part of my bed` is composed of the sidepieces K K, andcross-pieces L and M, said crosspiece M being bevelled ofi` on the underside, as shown in iig. 1, so as to clear the slats J J, and allow thehead part to come down to nearly a vparallel position with respect tothe bed-frame G G, when. desired.

The blocksan are secured to the frame-pieces K K, as shown, and thehinges c c pivot the head part to the ,block b on the main frame, asshown in figs. 1 and 2.

The edge springs C G and centre springs D D are of the same form as thesprings A- and B, and arranged, with their small ends downward, on thepieces L and M, as shown.

The elastic wire rim F has itsl ends f f secured to the blocks a a, andis secured to Ithe edge springs C G by the cords u and a1, which arearranged, with respect to the springs C and D, and frame K L M K, asindicated by red lines in gs. 1 and 2.

The frame-pawl-O P O is composed of the crossbar P, which is hinged byhinges d d to the frame L, and the pawls O O, which engage with notchesh Il,

-cut in the main frame-pieces G G, from which it is readily seen thatthe head part can be supported at any desired angle, the peculiarnt-ility of having the pawls O vO united by a cross-bar, P, consistingin the fact, that by this arrangement, both pawls can be operated atthesame time from one side of the bed, so that any desired adj nstinent ofthe head part can be easily eii'ected.

When the head part is to b let down, the frainepawl O P O is turned upunder the frame-pieces K K, and serves as a support for the head part onthe main frame G N G.

This bed may be covered with canvas, or other suitable material, ifdesired, the edges of said 'material being secured to the frame-pieces GH G and K L K, in an obvious manner; or, the mattress, or other bedding,may be laid directly on the tops of the springs, as may be founddesirable.

It is evident that the 'same system of combining the edge springs andcords with an elastic Wire rim may be applied to' the construction ofsofas, chairs, and

ses lo other articles constructed with spring-bottoms, and on whichv anelastic edge, whether straight or curved, would be desirable.

I do not claim as new the use of conical springs in the construction ofspring-beds, whether the large or small ends are placed downward; nor doI claim the lplacing of conical springs on slats of less elasticity thanthat by which they are enabled to take vthe place of the lower half ofthe double conical spring in spring'- bed construction.; nor do'I claimthe use of an elastic wire rim, except in combination with conicalspiral springs and elastic slats, constructed and arranged as hereindescribed; but having thus fully described myl cured thereto, cross-barI, spring-slats J J with slots l therein, lower-end frame-piece H withpins It' k therein, edge springs B B, centre springs A A, elastic wirerixn E E E, cording p p, 'r/r,t t, elevating hinge-blocks lt a, b b,hinges c c, head-frame K L M K with springs C C, D D, elastic rim F F,cording u n, and frame- -pawl O P O with axial hinges d al, the severalparts being constructed, combined, and arranged in the manner and forthe purposes herein specified.

lAs evidence that I claim the foregoing, Iliave hereunto set my hand, inthe presence of two witnesses, this 18th day of January, A. D. 1869,'
